The accumulation and utilization efficiency of nitrogen and phosphorus were studied using hydroponic cultures of seedlings of the ‘Presto’ and ‘Rhino’ D(A) and D(B) substitution lines of hexaploid triticale. The results were significantly affected by homoeology group of chromosomes participating in a substitution, the A or B genome origin of replaced chromosome and genetic background of triticale cultivar. The substitutions 4D(4B) and 5D(5B) resulted in an increase of plant dry matter in relation to the non-substituted cultivars. The significant increase of N accumulation was found in 3D(3A) and 4D(4B) of ‘Rhino’, and 5D(5B) and 4D(4B) of ‘Presto’. The improvement of N utilization efficiency was recorded for 2D(2A) and 1D(1B) of ‘Presto’, and 5D(5B), 7D(7A) and 5D(5A) of ‘Rhino’. The P accumulation was distinctly improved in ‘Presto’ 5D(5B) substitution. The P utilization efficiency was improved in all substitutions containing 4D or 6D as well as in ‘Presto’ 2D(2B) and 5D(5B).
